Accepted Answer

Hi,

Aurora PostgreSQL is not supported on db.t3.small. Please refer here https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/Concepts.DBInstanceClass.html#Concepts.DBInstanceClass.SupportAurora for the supported instance classes vs the DB Engines. On the db.t3 – burstable-performance instance classes, only db.t3.large and db.t3.medium are supported for Aurora PostgreSQL, on versions 14.3 and higher, 13.3 and higher, 12.7 and higher, 11.12 and higher.

Hope this helps.

Thanks,
Arun
